Determinando Nitrato Lixiviado com Sacos com Resina

Incubação do saco com resina

Princípio

Pequenos sacos com diâmetro fixo são preenchidos com resina trocadora de ânions: um material granular no qual todo nitrato que entra em contato é adsorvido. Esses sacos são incubados em uma certa profundidade no perfil não de solo não alterado, a fim de que todo nitrato lixiviado acima do saco seja retido no saco. Após a incubação, o nitrato é removido da resina por meio de lavagem com KCl e sua concentração é determinada.
